hey,
its a hybrid pre-amp Pyle P3201ATU, has red and white inputs labeled sub out 1 and sub out 2. i do not know the exact model of the sub, i bought it off kijiji.
thank you
Yes, those are the subwoofer outputs, but you can drive only an active subwoofer, meaning your sub should have a built-in amplifier and therefore it should have a power cord. Most likely you must buy an additional power amplifier for your sub (post a picture with the sub' input panel or label, to properly make an amp recommendation).
